It's mildly clunky but it is possible to export the model to a PMML file, read it back in and then parse it using XPath.
There's an example using decision trees at this link.
문제
I would like to run a simulation that depends upon Linear Regression Model coefficients.
In RapidMiner, how could I extract the Linear Regression Model coefficients?
I would find it very useful if I could get those coefficients into macro parameters?

The recently released Converters Extensions, available at the RapidMiner marketplace, has an Operator for this. Take a look at the Linear "Regression Model to ExampleSet", it will return the coefficients as an ExampleSet.
